Description
This is a part for a specific bit system; check the diameter, thread and compatibility before ordering.
EHWA Coupling (Head)
A coupling head is the connecting piece in a modular core bit system, joining the tube to the drill or to an extension. It carries the thread that makes the bit usable on a core drill rig.
Key Features
- Match the diameter and thread to the tube and to your drill
- Clean and lightly grease threads for easy assembly
- Tighten firmly before use; a loose joint damages threads
- Inspect for worn or damaged threads and replace if needed
